This was a wonderful experience! You put a ton of personal touches and love into this, and it shows. The beginning and ending cutscenes were well done and a nice touch. I loved everything about this! Your team should be very proud of what you made! Great work on the creepy atmosphere. Theme was well implemented as well as your game being original and well made. Bravo!

Advice for the Future / Feedback for improving this game:
- Play around with the oxygen functions. Have a item pickup that refills the O2? This will add an extra element to the game.
- Following the Metroid formula, you could have the Captain have no weapon or breach charges, has to find them. They unlock new parts of map. https://www.gamasutra.com/blogs/HugoBille/20120114/90903/The_Invisible_Hand_of_S... nice level design layout of Super Metroid for inspiration.
- Continue adding more story that leads the Captain deeper and deeper into the cave and maybe a boss fight that leads into the discovery of the planet's secret.
